Air Star Service's team of certified technicians keeps abodes in harmony with internal thermostats by tuning up heating and cooling systems from any brand, including Goodman and Honeywell. Specialists in indoor air quality stock trucks with brand-name parts before setting out to boost the performance of home systems. More efficient climate control can improve home efficiency and pamper Mother Nature like an obedience class for Smoky the Bear. The crew braves furnaces' fiery depths to run and test heaters, track down gas leaks, scour mechanical innards, and lubricate creaky cogs. Air-conditioning units unfailingly chill inside atmospheres after technicians test-drive units and purge cumbersome gunk from condenser coils and drain pans. Fresh filters sub in for grimy predecessors as temperature experts scrutinize compressor- and condenser-fan motors, wiring, and refrigerant levels in search of ailing areas and befuddled arctic explorers.
